CARL H. BISSELL, or SYRACUSE, NEW YORK, ASSIGNOR To cRoUsR-nINnsCOMPANY, or SYRACUSE, NEW YORK, a CORPORATION OF NEW YORK.

COMBINED FUSE AND SWITCH' BLOCK.

Application filed Aprifl 30, 1920. Serial No. 377,950.

To all whom it may concern:

Be it known that I, CARL H. BissnLL, a

citizen of the United States, and a resident of Syracuse, in the countyof Onondaga and State of New York, have invented a certain new anduseful Combined Fuse and Switch Block, of which the following is aspecification.

This invention has for its object a combined fuse block and switch whichpermits a particularly simple efficient and compact arrangement of thefuses and switch mechanism, and also a simple and compact arrangement ofthe handles and fastening means by which the block is placed and securedin. a box as the box connected in an electrical conduit system which boxor the opening through which the block is placeable and removable is ofthe same shape and slightly greater in size or areathan the fuse block.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is a plan view, partly broken of this combined fuse block andswitch.

Figure 2 is a plan view of the base block, the fuse contacts, switchmechanism, and cover for the switch being removed.

Figure 3 is a sectional view on line 33, Fig. 2, the switch cap beingincluded.

Figure 4 is an inverted plan view of the base block.

Figure 5 is an inverted plan View of the cover for the switch base.

This combined fuse block and switch comprises a base block of insulationhaving a substantially plain or fiat face on one end portion or halfthereof, an integral switch base rising from the other end portionthereof, fuse contacts on said face, switch mechanism in the switch baseincluding wire terminals and terminals connected to one set of fusecontacts, and a' cover for the switch.

1 designates the base block which is usually formed of porcelain and isrectangular or oblong in form. 2 is the face on which. the sets of fusecontacts 3, 4 are mounted. 5 is the switch base which is circular or ofsuch shape that it recedes at 6 and 7 respectively from the side edgesof the block toward the central part and one end of the block, leavingspaces at 8 and 9 respectively for handles and for fastening members bywhich the block can be placed into aboX or cover opening in one side ofthe box of the same shape and but slightly larger than the area of theblock.

The device, here illustrated, is adapted for a'three wire system and isprovided with contacts for three fuses mounted on the face 2 and thepairs of contacts for the respective fuses are separated by barriers 1Ointegral with the block and extending lengthwise of the face 2 from theswitch base 5, said barriers having cutouts 11 between their ends forfacilitating handling of the cartridge fuses when being inserted andremoved. Said contacts are secured in position in any suit able manneras by screws 12, 13 extending through the block from the rear sidethereof through holes 14, 15, the screws 1 also extending through wireterminals 16 connected to the contacts 3.

The switch mechanism may be of any suitable form, size and construction,it being of any standard. form ofsnap switch. Said mechanism includeswire terminals 17, 18, 19, located at different elevations on the baseand having switch contacts associated therewith, terminals 20, 21, and22 for connection .with one set of fuse contacts a, and having switchcontacts paired with those of'the wire terminals 17, 18, 19, switch arms23, 2 1, 25 for connecting and disconnecting the terminals 17, and 20,18 and 21, 19 and 22, and a rotary operating member or stem 26 extendingthrough the top of the cover 27 for the switch base.

The base 5 and cover 27 are formed with suitable cutouts 28 28 by whichthe line Wires can pass to the terminals l7, 18, 19.

The cover is secured in position in any suitable manner as bydiametrically located screws one of these screws being shown anddesignated 29 and the hole for the other screw being shown. Theterminals 20, 21, 22, are connected to the fuse contacts i by conductorsor wires located in grooves 30 in the bottom side of the block, saidwires extending through hollow screws 31 to binding screws on theterminals 20, 21, 22. Said screws extend through the base from the rearside thereof and are located in holes 32.

The handles by which the block can be tening screws. By reason of thelocation of the screw holes the screws can be driven and removed throughthe cover opening which, as before stated, is of nearly the same size asthe base block. 7

An additional screw hole 36 is provided substantially central of theface 2. It is apparent that by reason of the relative arrangement of thefuse supporting surface 2, the switch 5, the handles or cutouts 33, andthe holes 35, 36 for the fastening screws, the device can be readilymounted in a confined space.

This fuse block and switch is especially adapted to be used in a boxsuch as shown in my pending application Sr. No. 111,688, filed July 27,1916 which has become Patent No. 1,350,486, granted August 24, 1920, andthe stem 26 or operating member is provided with a coupling section as across pin 37 arranged to coact with a complemental section on the stemof a rotary handle provided on the cover of the box.

that I claim is:

-1. A combined fuse block and switch comprising a rectangular basehaving a substantial fiat face on one end portion thereof, and acircular switch base rising from the other end portion thereof, the baseblock being formed with recesses in the opposite margins thereof locatedat points where the switch base recedes away from the edge of the baseblock toward the central portion of the block, substantially as and forthe purpose described.

2. A combined fuse block and switch comprising a rectangular base havinga sub stantially flat face on one end portion thereof and a circularswitch base rising from the other end portion thereof, the base blockbeing formed with recesses in the opposite margins thereof located atpoints where the switch base recedes away from the edge of the baseblock toward the central portion of the block, and with holes forreceiving fastening members located at the corners of the base blockadjacent the switch base at points Where the switch baserecedes from theside edges of the base block toward the end edge thereof, substantiallyas and for the purpose specified.

3. A combined fuse block and switch comprising a rectangular base havinga substantially flat face on one end portion thereof and a circularswitch base rising from the other end portion thereof the base blockbeing formed with recesses in the 0pposite margins thereof located atpoints where the switch base recedes away from the edge of the baseblock toward the central portion of the block, and with holes forreceivlng fastening members located at the corners of the base blockadjacent the switch base at points where the switch base recedes fromthe side edges of the base block toward the end edge thereof, the baseblock being also formed with an opening for a fastening member locatedin the central portion of said flat face, substantially as and for thepurpose set forth.

.4. A combined fuse block and switch comprising a rectangular basehaving a substantially flat face on one end portion thereof, a circularswitch base rising from the other end portion thereof, and barriersrunning lengthwise of said face from the switch base, finger receivingrecesses in side 1nargins of said base block located at points where theswitch base recedes from the side edges of the block toward the centralpart thereof, holes for fastening members located in the corners of theblock adjacent the switch base where it recedes from the side edgestoward the end edge of the block, and an additional hole for a fasteningmember located in the central partof said face, substantially as and forthe purpose set forth.

In testimony whereof, I have hereunto signed my name, at Syracuse, inthe county of Onondaga and State of New York, this 30th day of March,1920.

CARL H. BISSELL.
